A. Vesicles returning backward to the ER
B. Secretory vesicles destined for the plasma membrane
✓
C. Proteins entering from the nuclear envelope
D. Lipids entering from the mitochondrial matrix

📝 Explanation

The trans-Golgi network is the sorting hub where exit vesicles are packaged and targeted to the plasma membrane, lysosomes, or extracellular space.
